To all ywhom it may concern.'

Be it known that l, LORNE A. GRIFFIN, a citizen of. the United States, residing at Elkhart, in the county-of Elkhart and State of' lndiana, have invented a new and useful lm provementin Pipe-Fittings for Materiah Conveying Lines, or Conduits, of Which the Al'ollowingis a specification. A

The invention relates to an improvement in Ts or pipe connections lines or conduits built Jfor conveying materials 'of variouslkinds at Vgreat speed by either the blast"or"vacuum system., or a connv bination of both systems, and especially to thevconveyance 'of materials of high abrasive plalities (in-account of which rapid ivear of the conduit pipe and'fittings results.

Theobjects of my invention are, first, to provide a T fitting having a removable wear taking liner,'or liners; second, to provide a T of the charactermentioned in which the` 'wear takingliner replacements may be made without *the removal of the T body itself from the pipe videra conduit is adapted to be usedas a feed hopper a conduit of' the characterl mentioned.

Figure 1 'is av side elevation of the'l" fitting T .fitting the branch of which for in section-With the hopper cover in position,

and having its wear taking liner in three seca section through the T fittingion the line B-B of Fig. 1. Fig.y 3 is a section through the T fitting on the line A .l of Fig.` 1 showing the hopper cover in side opening cover plate and liner in position. Fig. il is a frag nientary section similar .to Fig. 1 ot the T when' theliner is made in-one piece. Fig. a section onthe line B-B'of' Fig. 1

through a 'T having its liner in one piece only, showing the liner and side'cover plate in position. Fig. (l is a sectionthrough the pipe litting on the line C -C of- Fig; l showing the liner partially withdrawn fromthe here of the T body and the side plate moved. f

Similar numerals refer to similar parts throughout the several views.

ln the drawings Figs. 1, 2 tions of a T having .a wear taking liner in three segmented pieces. Figs. 4 and 5 show sections of a T body with a single piece liner` et -seppnental form arranged within said T and occupying less than the length of the bore thereof.

ofpipe connection is shovvnin Figs. 1 andr 2 -wherein the` Wear taking liner is segmental, eccentric and occupies the full length of the i.'

borel thereof.

The cover 2 operates as ra sealforthe hopper opening l'oif the branch or lateral of saidT.' And the side plate 6 seals the open;

ing 1d after the insertion of the Wear taking'- liner, or liners, into the bore of the T. T he T 1 has openings 1 and 1", and flanges 8 and 9 for pipe line connection in any Suitable manner.

The liners e, 4 and 5 in rigs. i arid 2 Vcarry lugs 3i* and 3b, la and 5 respectively.

'Vhen the one piece liner 3 is used, .as in thereon at or near asshown.

rlhe'hopper cover plate 2 the extremities thereof,

has a handle 2 formed thereon in any suitable'manner, and' a conical face 12 which sealsthe opening 1 when surface 12 contacts with the comcal" at suchfan angle that no materials can collect thereonto make an imperect'and leaky seal or joint between the face 12 of the eove'i` 2 and the conical seat 11. y

The hopper flange 10'may be laterally extended as at 10LrL for building in flushwith the i' i surface( of a door of cement or other material. The branch opening, or hopper, 1c is placed closer to one end of the T body than to the other in order that the abrasive actionl ofy the materialsentering the hopper may al- 'ways be expended upon and taken up by the liners of the fitting. rThe linersl 3,r 4 and 5 ofV Figs. 1 and and eccentrically, as shown, for the most of or thickest part of the' liner. Liner 3 has edges 13 and 13 which engage with shoiilders 14 and 25 respectively, interiorly :formed in` said T loody.4 Liners 4 and 5 are concaved to the same circle or radius'usefl .for liner 3 and have their edges 15 and 1G for engagement with the shoulders 111v and 25 of the T body. The

t and 5, lugs 3 and 3" are formed'.

abrasion occurs at the bottom.

f9.5 Y. 2, as well as liner 3 of Figs. l and 5, are preferably formed segmental lowerY halfpof the lo'ody 1, both interiorly and exteriorly, is 'I built to accommodate the eccentricity of the segmentedliners.

At one side of the body 1.is formed vthe lliner opening 1f1 for the insertion and removal of the wear taking liners. This openi ing is sealed-by cover plate 6 as shown at 111g. 3 and Fig. 2 by the use of studs or bolts 7 and 7. When but one liner is used, as in Figs. 4, and 5, .ii-t is inserted through opening ld to the interior of the T body 1, leaving the lugs 3** and 3b projecting back- Ward approximately to the edge of the opening 1a. hen cover plate 6 is bolted over opening ld the inside face 22 of said plate presses against'the end 21 of lugs 3a and 3",

there y forcing projection 13 and 13 of the liner tightly against shoulders 14 and 25.

plate 6 by virtue of the pressure brought opening l until 5a contacts' witli'the shoulder 20 to bear on the face 21 of the lugs 3i and 3b of liner section 3, lug 4J* of the liner section 4 and lug 5B of liner section 5. The liners '3, 4 and 5 are arranged Within the T body singly and asfollows. Cover plate 6 having een removed, liner 3 is inserted through 1d the edge 13 is infull engagement with the shoulder 14, when the liner is projected laterally toward opening l'tuntil the shoulder 17 of lug 3a contacts with the shoulder 18 of the T body 1. Then will the outside end of the liner 3 and the face of the flange Liner 5 is thereupon inserted in the same manner and to the'saine extent as liner 3 and projected to the right toward the shoulder 19 of the lug of the' body of the T 1. hen Will the outside end of liner` 5 be flush with the face of iange 9. Liner 4 may then be inserted between 3 and 5.

What I claim is A1. In a T .through said sideopening and subsequent 'ment and within the T body longitudinal projection to the main openings of the T interior, and a cover said lateral opening and adapted to engage 'd Wear section lugs to retain the Wear sections against lateral movement.

n a connection for material conveying conduits the combination of a T body provided With a branch opening removable cover for the branch opening, an opening in the side of the T body, a removable segmental wear section arranged Within the T body and provided with laterally' projecting lugs, and a'cover plate sealing saidlateral opening and adapted to engage .the Wear section'lugs to retain same against lateral movement.

3. In a T connection for material conveying conduits the combination of a T body provided with a branch opening removable cover for the branch opening, an opening formed in the side of the T body, an enlargement of the T body formed in the lower portion thereof, a plurality of removable Wear sections arranged within the T b carried by SaidenIargement, two

limiting the'longitudinal movement thereof ivithin the T body, a cover plate for sealing said lateral opening, and means for securing the cover plate in position.

In a T connection for material conveying conduits the combination'of a T body provided with a branch opening removable cover for the branch Wear section arranged Within said enlargen and provided -with laterally projecting lugs, an opening 5 inthe side of the body adapted for the LoRNE A. GRIFFIN.
